Hi, R-users,
I have a problem: Because there are few files which can't be readed
into R completely, so on the following subsequence programme, I use
write.table, which creates the "NA" files for those incomplete files
autimatically.
I don't want those NA files.
My programes formats looks like:
name_c<-Sys.glob("C:/Documents and Settings/lma/My
Documents/habitdata/*/calllog/*")
for (i in 1:length(name_c)){
log1<-readLines(name_c[i])
....
write.table(Temps, file=paste("C:/Documents and Settings/lma/My
Documents/habitdata1",pname,lname,basename(name_c[i]),sep="/"))
}
Error Information:
Error in file(file, ifelse(append, "a", "w")) :
cannot open the connection
In file(file, ifelse(append, "a", "w")) :
cannot open file 'C:/Documents and Settings/lma/My
Documents/habitdata1/NA/NA/NA': Permission denied
I have checked why the error appears, because when I use "readLines" to read
data, but when processing the large data set, there are few files which can not
be readed in completely:
48: In readLines(name_c[i]) ... :
incomplete final line found on 'C:/Documents and Settings/lma/My
Documents/habitdata/244052900243997/calllog/calllog_log-20050505T121611.txt'
...
So it create the "NA" file when implementing the subsequence procedure by
write.table.How can I do: whenever readLines can't completely read one file,
then autimatically doesn't implement the subsequence programmes?
Thanks.
Tammy
